The Reds selected Busenitz's contract from Triple-A Louisville on Friday.

He'll give the Reds a fresh relief arm after the bullpen needed to cover five innings Thursday against Atlanta. Busenitz gave up four runs (three earned) in one inning of work in his lone appearance with the big club in 2024.

The Reds optioned Leibrandt to Triple-A Louisville on Friday.

Leibrandt was pummeled for seven runs over four innings in an extended relief appearance Thursday versus Atlanta. He's being replaced on the roster by Alan Busenitz, who gives the bullpen a fresh arm.

Adon (biceps) was transferred to the 60-day injured list Friday.

The right-hander landed on the injured list in late August due to a biceps strain, and he won't be eligible to return for the final stretch of the season. Adon made one start in eight appearances with the Nationals this year and posted a 6.75 ERA, 1.50 WHIP and 6:4 K:BB over 10.2 innings.

The Nationals optioned Brzykcy to Triple-A Rochester on Friday, Mark Zuckerman of MASNSports.com reports.

The rookie reliever is clearing out to make space on the roster for Trevor Williams, who is back from the injured list to start Friday's game against the Cubs. Brzykcy was roughed up for nine runs over 5.2 innings during his brief first stint in the big leagues.

The Cubs designated Armstrong for assignment Friday, Meghan Montemurro of the Chicago Tribune reports.

The Cubs claimed Armstrong after he had been jettisoned from the Cardinals' 40-man roster and the veteran reliever will now go through the waiver process again. Armstrong yielded four runs with a 4:4 K:BB over 7.1 frames during his brief time with the Cubs.

The Cubs activated Wesneski (foreram) from the 15-day injured list Friday, Meghan Montemurro of the Chicago Tribune reports.

Wesneski has been sidelined since late July with a right forearm strain but has been cleared to return after making four rehab appearances with Triple-A Iowa. He's pegged for a multi-inning relief role with the Cubs down the stretch.

Romero (7-3) allowed a run on one hit and one walk over two-thirds of an inning, taking the loss Thursday versus the Pirates.

Romero put two runners on base in the eighth inning, and Ryan Fernandez allowed one of them to score after he entered the game. Over six innings in September, Romero has allowed two runs on six hits and three walks, a slight fade in performance from his level throughout the year. He's now at a 2.76 ERA, 1.09 WHIP and 51:15 K:BB through 58.2 innings while adding a save, eight blown saves and 30 holds.

Chapman earned a save against the Cardinals on Thursday, allowing one hit in one scoreless inning.

Chapman entered in the bottom of the ninth inning with a one-run lead and gave up a leadoff single to Brendan Donovan. However, Donovan didn't advance any further, as Chapman retired the next three batters on just four pitches. Chapman has converted each of his past four save chances, though this was just the second time in that span that he hasn't allowed a run.

Ortiz allowed two runs on five hits and two walks while striking out seven batters over six innings in a no-decision against St. Louis on Thursday.

Ortiz held the Cardinals scoreless over the first three innings before St. Louis put up a run in the fourth and another in the sixth. The right-hander notched his sixth quality start of the campaign, which is more impressive when considering that only 14 of his 36 appearances have come as a starter. Ortiz also tied his season high with seven punchouts Thursday, a mark he's now achieved three times.

Walker (9-4) allowed two runs on two hits and struck out two over two-thirds of an inning to take the loss Thursday versus the Orioles.

Walker allowed multiple runs for the first time since July 9 as he gave up a walk-off, two-run home run to Anthony Santander in the ninth inning. The Giants' closer had not given up an earned run over his previous 20.2 innings, and he entered Thursday on a 12-inning scoreless streak. He avoided a blown save since this misstep came in a tie game. Walker has eight saves, four blown saves and 22 holds with a 1.99 ERA, 0.86 WHIP and a 98:17 K:BB through 77 innings this season.
